ATTORNEY aiented Aug. 2, 1949 UNITED STATES 'ATENT OFFICE William J. Mervenne, Grand Rapids, Mich., as-

signor to Clipper Belt Lacer Company, Grand Rapids, Mich.

Application November 18, 1948, Serial No. 60,699

6 Claims. (01. 149.4)

This invention relates to improvements in belt lacer fastener applying tools.

The main objects of this invention are:

First, to provide a belt lacer applying tool of the hand type which is eificient in simultaneously setting or applying a plurality of fasteners to a belt and at the same time may be easily manipulated by relatively inexperienced workmen.

Second, to provide a tool of this character which is light in weight and at the same time is a hand actuated tool capable of applying necessary power to set a plurality of belt lacing fasteners of the type commonly designated as belt hooks.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illlustrated in the accompanying drawings, in which:

Fig. 1 is a side elevational view of a tool of my invention with the acuating member in actuated position.

Fig. 2 is a fragmentary top plan view.

Fig. 3 is a side elevational view partially in longitudinal section with the actuating member in open position and belt fasteners and a belt shown in position preliminary to closing the jaws.

Fig. 4 is a fragmentary view in section on a line corresponding to line 4-4 of Fig. 3.

In the accompanying drawing i represents one end of a belt and 2 a belt lacing hook or fastener. The embodiment of my invention illustrated comprises a body member, designated generally by the numeral 3. and having a handle portion i and head portion 5. This body member is of channel section. The head 5 is provided with laterally projecting flanges '6 at the face of the head.

The actuating member I is pivotally mounted at 3 within the body member and is yieldingly held in retracted position by means of the spring 9 connected thereto at one end and at the other end to the handle, the connection to the handle not being shown. The actuating member is actuated by a toggle consisting of the lever Ill pivoted on the actuating member I at l l and the link l2, one end of which is pivoted within the handle at [3 and the other to the lever at M. The lever is positioned to be grasped with the hand grasping the handle. The relatively fixed jaw member 34 is secured to flanges 5 by means of the screws 85, This jaw member has inwardly projecting arms It on which the swineable jaw member I1 is pivotally mounted, the swingable jaw member l1 having inwardly projecting arms I8 disposed at the sides of and in overlapping relation to the arms [6 of the fixed jaw member.

The fastener holder support 19 is provided with forwardly projecting arms or pivot ears 29 disposed at the outer sides of the jaw arms. This fastener holder support is desirably formed of sheet metal as illustrated and has inturned flanges 2| on its longitudinal edges. The fastener holder block 22 is arranged on the support between the jaw member arms. The pivot rod 23 is arranged through the jaw arms and the pivot ears of the holder support and also through the holder support.

A cotter pin 24 disposed through the fastener holder block and the pivot pin retains the parts in assembled relation. The holder block is provided with a plurality of transverse slots 25 adapted to receive the bight portions of the fasteners 2. A retaining pin 26 is arranged through the slots to engage'the bights, as is shown in Fig. 3, thereby retaining the fasteners in position to receive the belt and as shown in Fig. 3 between them.

The actuating member has a flat jaw engaging face 21 which when actuated first engages the curved edge 28 of the swingable jaw swinging it with a camming movement to closed position in which the side 29 of the jaw and the abutment face of the actuating member are in parallel relation, as shown in Fig. 1, thereby relieving the parts of undue stress when the fasteners are brought to completely set position.

Sometimes it is desired to use the tool for setting fasteners of different dimensions and in that case another holder member may be substituted for the holder member 22. The fastener retaining pin 25 is provided with an eye 39 connected by the chain 30 to the end of the pivot rod so that it is not likely to be misplaced or lost which is a matter of convenience in view of the fact that the tool of my invention is designed to be carried about for use on the job, for example by farmers, machine tenders or operators and the like.

I have illustrated and described my improvements in an embodiment which is highly practical. I have not attempted to illustrate or describe certain adaptations and modifications which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A belt lacing tool comprising a handle having an integral head provided with laterally projecting flanges, a jaw actuating member pivotally mounted on said handle, means for actuating said actuating member including a lever adapted to be grasped with the handle, a relatively fixed jaw member secured to said flanges of said head and provided with longitudinally spaced inwardly projecting arms, a coacting swingable jaw member provided with longitudinally spaced pivot arms disposed at the sides of the arms of said fixed jaw member, a fastener holder support having forwardly projecting pivot ears at its ends disposed at the outer sides of said jaw member arms, a fastener holder disposed on said support between said jaw arms and slotted to receive the bights of a plurality of fasteners, a pivot rod disposed through said arms on said jaw members and said ears on said fastener holder support and extending longitudinally through said fastener holder whereby the several parts are supported and retained, a retaining pin for said rod disposed transversely through the fastener holder and the rod, said actuating member having a jaw abutment coacting with the swingable jaw for sliding and clamping engagement therewith.

2. A belt lacing tool comprising a handle having an integral head provided with laterally projecting flanges, a jaw actuating member pivotally mounted on said handle, means for actuating said actuating member including a lever adapted to be rasped with the handle, a relatively fixed jaw member secured to said flanges of said head and provided with longitudinally spaced inwardly projecting arms, a coacting swingable jaw member provided with longitudinally spaced pivot arms, a fastener holder support having forward- 1y projecting pivot ears at its ends, a fastener holder disposed on said support between said jaw arms and slotted to receive the bights of a plurality of fasteners, a pivot rod disposed through said arms on said jaw members and said ears on said fastener holder support and extending longitudinally through said fastener holder whereby the several parts are supported and retained, said actuating member having a jaw abutment coacting with the swingable jaw.
